PERFORMANCE OF CORN HYBRIDS IN ALABAMA, 
1982'
INTRODUCTION
Corn hybrids are evaluated annually by the 
Alabama Agricultural
Experiment Station in the Regular Corn Hybrid Test 
and the Preliminary
Corn Test on a north, central, and southern regional basis. The Marion
Junction, or Black Belt Substation, corn test is 
used as the prairie
soil regional comparison. Entries in the preliminary 
tests are both
experimental and newly released hybrids. If a hybrid 
is outstanding in
the preliminary test it is entered into the regular corn 
test the
following year. White corn hybrids are tested at one location 
in each
region. One regular and one white corn hybrid test are irrigated at
Headland in southern Alabama.
The locations and cultural practices for the tests are shown in
table 1.
The tests are designed as a randomized complete block with four
replication. Row width was 36 to 40 
inches depending on location.
Two-row plots were used with row length ranging from 20-30 feet
depending, again, on location. The target plant 
population for the
tests was 20,000 plants per acre with a seeding 
rate of 23,000 seeds per
acre. The irrigated tests at Headland were seeded 
at a rate of 30,000
plants per acre and thinned to 
26,000.
Grain yields were adjusted to 15.5 percent moisture 
and converted
to bushels (56 pounds) per acre. Stalks broken 
or leaning more than 45
degrees were considered lodged. The 
mid-silk date measured the number
lOrganized and compiled by Cliff Currier, 
W. C. Johnson, and
Darrell Williams.
-1-
of days from planting until one-half of the plants in the plots were
showing silks.
The corn hybrid tests are examined for disease incidence each year
by Dr. R. T. Gudauskas, Department of Botany, Plant Pathology, and
Microbiology. When virus or other disease symptoms indicate crop
damage, disease ratings are compiled and published in this report.
Virus infection data from the tests at Marion Junction, Winfield, and
Belle Mina are reported this year.
To aid in determining real yield differences, a statistical
analysis of variance is performed on the data from each location. The
L.S.D. (least significant difference) and C.V. (coefficient of
variation) are given for each location's 1982 test. The difference in
yield of two hybrids must exceed the L.S.D. value for one hybrid to be
considered superior to the others in yield in that particular test. The
C.V. is a measure of test variability. An increase in its value
indicates a decrease in the reliability of the data.
Since the performance of hybrids varies with location and year,
long-term averages from several locations are more reliable than 1-year
performance. Three-year regional averages are considered a reliable
evaluation of the relative performance of hybrids.
A composite rating system was used to assemble a list of acceptable
hybrids. The 3-year regional average grain yield was used as a base
point. The composite score was obtained by subtracting weighted values
for lodging, quality, and ear height from the yield.
The recommended hybrids are not all equal in performance. Some are
outstanding in one or more characteristics; while others may not be
-2-
obviously outstanding, they might possess a satisfactory combination of
all characteristics.

VIRAL DISEASE RE." TIONS OF SOME HYBRIDS IN 19821
The two most prevalent viral diseases of corn in Alabama are maize
chlorotic dwarf (MCD), caused by the maize chlorotic dwarf virus (MCOV),
and maize dwarf mosaic (MDM), caused by the maize dwarf mosaic virus
(MDMV). Discovery of MDM in the State dates back to the early 1960's,
while MCD has been recognized only since 1973. Both diseases probably
occur throughout Alabama; however, they generally have been more
prevalent and damaging in the northern two-thirds of the State.
Symptoms of the two diseases are similar in appearance and some-
times difficult to distinguish. Generally, affected plants are chlorotic
or discolored and may be stunted. Leaves of MDM-diseased plants show an
irregular, light and dark green mosaic or mottle; the initial symptom of
MCD is a fine, chlorotic streaking over the smallest veins.
The causal viruses are spread by feeding activities of insects.
MCDV is transmitted by certain leafhoppers, and MDMV is carried by some
aphids. Both viruses have simil'ar host ranges among a variety of wild
and cultivated grasses. Johnsongrass is an important overseason or
reservoir host for the viruses, and MCD and MDM incidence and damage
usually are high in corn fields that are heavily infested with
johnsongrass.
Use of resistant or tolerant corn hybrids and the control or
avoidance of johnsongrass infested areas are the most practical controls
for MCD and MOM. Commercial and experimental hybrids are evaluated
yearly to identify resistant hybrids or promising sources of resistance
Prepared by Robert T. Gudauskas, Department of Botany, Plant
Pathology, and Microbiology.

to the diseases. Results of evaluations of some commercial hybrids
during 1982 are summarized in this report.
PROCEDURE
Viral disease ratings were made on entries in the corn hybrid test
at the Black Belt Substation, Marion Junction, the Tennessee Valley
Substation, Belle Mina, and the Upper Coastal Plain Substation,
Winfield. Plants showing symptoms of MCD and/or MDM were counted and
data are reported as percent incidence of the diseases for each hybrid.
RESULTS
At the Black Belt Substation (table 30), incidence 
of MDM ranged
from 0-31 percent among hybrids and averaged 3.9 percent for the entire
test; MCD was found in only three plants in the test. Several hybrids
showed no symptoms of either disease, e.g. DeKalb brand XL72BB, 
Funk's
brand G-4747W-1, Gutwein brand MDM 2885, McCurdy brands 81-35 and 8225,
and Pioneer brands 3147 and 3160. Incidence of either disease was less
than 5 percent in at least 16 other hybrids.
Incidences of MDM and MCD generally were low throughout the test at
the Tennessee Valley Substation (table 31).
In the'test at the Upper Coastal Plain Substation (table 32),
incidence of MDM ranged from 0-30 percent and averaged 6.5 percent
overall; that for MCD ranged from 0-21 percent and averaged 4.8 percent.
No symptoms of MDM or MCD were found in Northrup King brand PX95 and
Pioneer brand 3147 and 3320. Incidence of either disease was less than
5 percent in several other hybrids.
Hybrids showing relatively greater resistance or tolerance were
apparent. Under conditions of higher or lower incidence of viral
disease, hybrids would be expected to retain their relative ranking.
-34-
When selecting a hybrid, viral disease reactions should be taken into
account for areas where the diseases are known or suspected to occur,
along with consideration of yield and other characteristics given
elsewhere 
in this report.
